AD5757ACPZ Datasheet PDF - ADI

Product Details

●The AD5757 is a quad, current output DAC that operates with a power supply range from 10.8 V to 33 V. On-chip dynamic power control minimizes package power dissipation by regulating the voltage on the output driver from 7.4 V to 29.5 V, using a dc-to-dc boost converter optimized for minimum on-chip power dissipation.

●Each channel has a corresponding CHART pin so that HART signals can be coupled onto the current output of the AD5757.

●The part uses a versatile 3-wire serial interface that operates at clock rates of up to 30 MHz and is compatible with standard SPI, QSPI™, MICROWIRE™, DSP, and microcontroller interface standards. The interface also features optional CRC-8 packet error checking, as well as a watchdog timer that monitors activity on the interface.
